many, have invented new and useful Improvementsin Adjusting Devices for Pattern-"Cylinders of Printingdlllachines, of which the following is a specification.

Is -rot ry machines for printing upon paper-pend, fabric in lengths, the relative adnan-est of the printing or pattern cylin- ".ders could only be efiected by means of the fr'egt ators arranged at the ends of the spindle'sw'of the pattern cylindei's. This adjustment of the cylinders, particularly in multicolor printing machines, was Very tedious and the adjustment for the correct printing of the patterns in such machines could only be effected by skilled printers.

According to the presentinvention the method of setting the pattern cylinders 1s such that the adjustment of the patterns becomes scarcely a matter for the printer and the working of multicolor p hinting machines presents no further difficultly, as the masterprinterno longer needs tch employ skilled men for this particular wprk. The usual regulator mechanism is no er employed according to the present inve tron for adjusting the patterns, but only in the last stagefor eliminating any irregularities due to faulty work by the die sinker.

The invention is illustrated in the accom-.

.panying drawings, wherein' "Figures 1-4 show dlagrammatlcally the arrangementof a printing machlne for 1nstance with four pattern c linders, while Fig. 5 shows a top plan view/ hf part of such a machine. 1

The regulatormechanism is of a known type'and is marked a 1n Fig. 5.. 'The centrahdisk of the machine is made of exactly the same circumfuential size as the impression cylinder 0. The central disk I) is formed with as many holes (I. II. III. IV) as there are color or pattern cylinders 6 6 ,6 It is essential that the distance apart of these holes (I. ll. III. IV) should correspond with the angular-distances apart around the central axes ofthe pattern cylinders; Hence, the following pairs of an:

gles' must be equal: ca -(5, 8:5 C, as

' they obviously are in the example shown Specification of Letterslatent.

Tn 4 Figs; 1-4, pattern cylinders c}, 6?, eflgcflof 1 v two dlfi'erent sums are ndicated n each oli the positions, in order to show. that any size of pattern cylinder may be used provided that all the cylinders are ofproper. relative sizes/so that the patterns .will repeat correctly. .On a convenient fixed part of the frame M a socket d isprovided (Fig. 5)

of the same size as the holes I. TLIII. IV. A pin 7 can be inserted. through each of the holes successively into the socket d in order .to lock'the central disk 6 in four positions which are indicated in Figs. 1, 2, .3 and: 4;.

In previous machines this was not the case,.as it frequently occurred that thepattern cylinders had been inserted in a false position" equivalent to half a turn error, and they were only brought nto correct register after hours had-been spent in adjustments.
